Suppressing Breadcrumbs
SUPPRESSING ALL THE BREADCRUMBS BELOW THE HEADER ol#s-lib-bc-list { display:none; }
If suppressing breadcrumbs moves the guide title too close to the Cornell banner you can add some breathing room with this code (where the "n"s represent a pixel value):
#s-lg-guide-header-info { margin-top: nnpx; }
SUPPRESSING JUST THE CURRENT PAGE BREADCRUMB li#s-lib-bc-page { display:none; }
